PNEUMATIC LINT CLEARER FOR- WABPING MACHINES AND THE LIKE.

Application filed March 12, 19 23. Serial No. 624,368.

To all w 720m it may concern:

Be it known that we, FRANK B. KENNEY and JOHN TV. SIDEBoT'roM, citizensof the United States, residing at Lowell, in the county of Micldlesex,State of Massachusetts, have invented a certain new and usefulImprovement in Pneumatic Lint Clearers for lVarping Machines and thelike, of which the following is a specification, reference being hadtherein to the accompanying drawings.

The invention is an improvement in pneumatic lint-clearing or removingdevices of the class of that described and claimed in United StatesLetters Patent No. 1,839,182- granted May 4, 1920, upon applicationofJames E. Farrell.

As in the case of the device of the Letters Patent just mentioned, adevice embodying the features of the present invention is applicable towarping machines, looms, and other machines in which a series of yarnsor threads travel onward side by side; and the improved device isadapted to serve the same general purposes as such formed device, namelythat of clearing lint from the yarns or threads, combs, guides,drop-wires, and the like, in the said machines; that of preventing lintfrom becoming attached to the yarns or threads so as to make slugs orbunches in the cloth into which the yarns or threads are Woven; and thatof preventing the stop motion mechanisms of the machines from beingrendered inoperative through clogging by accumulated lint.

The invention provides a lint-clearer device of simpler and lessexpensive character and construction than the device of the said LettersPatent- The latter includes a fan blower which is made to travel backand forth across the machine with which it is combined, by means of arotating traverse screw having an endless or right and left screwthread, suchtravel being designed to cause the blast or current of airfrom the blower to act uniformly at all points in the width of themachine. The fan blower of said Letters Patent also is mounted at aninclination in connection with its carriage, and is intermittinglyturned step by step around a vertical axis by means of pawl and ratchetdevices so as to send the blast or current in different directionssuccessively,

and thereby reach all portions of the yarns or threads and machine,front and rear, in turn.

In the case of a pneumatic lint-clearer embodying the present invention,the blower that is employed occupies a definite location in the machineto which it is applied, and has combined therewith moving means thereforby which the blower is swung transversely of the machine so as to causethe blast or current of air to play back and forth across the width ofthe series of yarns or threads; and by which, also, the blower isvibrated in a direction at right angles to such swinging movement so asto cause the blast or current to play forward and rearward in thedirection of the length of the yarns or threads.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, in which latter,

Fig. 1 is a front view of a portion of the width of a warping machinehaving the said embodiment applied thereto.

Fig. 2 is a side view of the machine and lint-clearer device of Fig. 1,certain parts having been removed on line 2, 2, of Fig. 1.

Fig. 3 is a view in vertical section in the plane of dotted line 3, 8,of Fig. 1, show ing a series of yarns or threads, the stop motiondevices, etc.

Fig. 4; is a partly sectional view on a larger scale, showing the blowerand a part of the means for oscillating the same.

Having reference to the drawings,

The drawings represent a typical warping machine and the arrangement,etc., of the lint-clearer device in connection therewith.

In Figs. 2 and 3, yarns or threads 1 are represented as extendingthrough the back comb 2 as if coming from a warper creel (not shown).The said yarns or threads pass from the back comb 2 over a measuringroll 3, under the movable falling rod 4, Fig. 3, over the supportingroll 5, through the front comb 6, and over the front supporting roll 7,from which latter they pass downward to the warper beam 8, whereon theyare wound by the action of the machine. Drop-wires 9, 9, 9, arerepresented as hung in the usual manner upon the yarns or threads atpoints between the rear support ing roll 5 and the front comb 6. At 11is the blower ofthe illustrated embodiment of the invention. It isshownapplied and arranged to operate to blow away lint from the yarns orthreads during their passage from rear to front at the top of themachine, and to keep the back andfront combs, drop-wires, and otherparts adjacent the drop-wires, in addition to the yarns themselves, treeand clear from lint.

In this embodiment of the invention the blower is mounted in .apositionabove the yarns or threads, etc, upon a support 10 in the torm of ashaft extendingaacross-the width of the machine, above the-top of thelatter, and mounted in bearings 100 in the upper endsof stands 111 uponthe tops of the .sideeframes of the warping :machine. Qnesotsuchstandsis partly .loroken.v away in Fig. 2. .Inthis instance theblower is located at .midwidthofi the seriesot yarns 01'. threads,whichis an 'efiective-position for enabling the blower torkeep the yarnsor threads-and the desired machine parts clear of lint,v and is anelectric/fan 11, whichiis preterred, although theinvention-isunotinecessarily restricted in all instancesto theiuse' otatan blower.

To; provide torswinning movements ot the said. fanll. transverselyof.the machine, it: is mounted between the depending-armsof a hail voryoke12, that-hangsdown TfPOD'l the supporting shaft 10, thetanwasing beingfurnished with journals 13, 13,working-in hearings in connection withthe said-harms. The bail or yoke occupies a vertical plane from thefan-casing, and havi-ngfixed onits outer end the disk or: plate 15,-azndalink 16 coupled at one of its-ends to a crank-pin 17, Fig. l, borne bythe, disklo, and at its other end to a pivot pin'lS, Fig. 1, 'fixed atthe outer extremity of a suitable member which is in turn fixed upon thebail or yoke 12, such as an arm 19 havlngthe attaching,portion thereoffixed .1,-11 a llO lQpP-OV-IQlQCl. for .it in ,one armot' the bail oryoke.

To provide tor. the convenient connection of the yoke with thesupporting. shatt.1-0,a

The bailor yokeis providedwith-ahub 40 which fits. upon the said stud. or pin, and a clamping screw 4-1applied-to the said "hub serves to holdithebail oryokeiinplace upon the.stud or pin, with capacity for adjustment up and idownto vary the heightof thefan. above: the yarns. or :theearlaete,

In this instance, welhknown devices, tuated by :the .no tatio nof thetan, itself, are

In this instance, such switch is indicated at 22, Fig. 3, locatedat the bottom of one end of the machine. The plunger 220 thereof isarranged to be depressed by a finger 23 upon the pedal rockshaft 24 toclose the switch and let the current flow only when the warping machineis running on high speed. In this manner just described the blower isautomatically set in action as soon as the warping machine is put onhigh speed and is caused to oscillate to direct its blast back and forthacross the width of the machine.
